Answer: The radius of the ball is 7 meters.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Surface area of a sphere: 4 π r^2
Replacing with the value given:
615.75 = 4 π r^2
Solving for r (radius):
615.75 /4π= r^2
√(615.75 /4π) =r
r = 6.99 = 7m (rounded)
The radius of the ball is 7 meters.
